Problem 18.1: A slow-motion representation of a sound wave propagating in Lucite

Please wait for the animation to completely load.

The animation is a slow-motion representation of a cross section of a sound wave propagating in Lucite. A detector, the orange square, is placed in the pipe and properly measures the pressure (position is given in meters and time is given in seconds). What is the speed of the sound wave? Note: The animation runs for 0.1 s. Press "reset" to reload the animation. Restart.
